MACHINE FOR POLISHING RODS.

Specification of Letters Patent.

Patented Oct. 23, 1917.

To all whom it may concern:

Be it known that 1, WILLIAM J. HEIN- A'Une, a citizen of the United States, residing at Massillon, in the county of Stark and State' of Ohio, have invented certain new and useful Improvements in Machines for Polishing Rods, of which the following is a specification.

This invention relates to apparatus for polishing bars or rods of circular cross section. One object of the invention is to provide an apparatus'by the use of which bars or rods of circular cross section may be rapidly polished without being deformed.

Another object of the invention is to provide an apparatus for the stated purpose in which the parts subjected to wear may be readily renewed and also to provide an apparatus in which the members directly engaging the rod or bar to be polished may be readily changed so as to conform to the diameter of the bar or rod.

Other objects of the invention areto provide means whereby the polishing material may be readily fed into chambers provided therefor, and also to provide means whereby the members containing the polishing material will be effectually held to the work. Other incidental objects of the invention will appear as the description of the same proceeds.

The invention is illustrated in the accompanying drawings and will be particularly pointed out in the claims appended hereto.

In the drawings: I

Figure 1 is a plan view of an apparatus embodying my improvements;

Fig. 2 is an end view of the same;

Fig. 3 is a longitudinal section;

Fig. 4 is a detail perspective view of the polishing block.

In carrying out my invention, I employ a cylinder or rotatable member 1 which is equipped at its ends with trunnions adapted to be journaled in suitable bearings, indicated at 3, which may 'be formed at the upper ends of standards rigidly secured in lace or maybe otherwise provided ma xed location. One of the bearings 3 is formed with an extension or lateral bracket 4 having one or more bearings 5 disposed with their axesat a right angle to the axis of the bearing 3, as clearly shown in F1gs. 1 and 3. The body orcylinder 1 is equipped at one end with a pulley 6 whereby motion maybe imparted to the body, as will be readily understood, and this pulley 6- may be formed integral with the body or cylinder, as shown, or may be otherwise fixed thereto, as will be readily understood. The body or cylinder 1 is bored axially, as shown at 7, and feed rollers 8 are disposedin the vertical plane of the said bore and above and below the horizontal plane of the same so thata rod or bar placed between the said feed rollers will be directed into the bore and when the rollers are rotated will be fed through the same as will be readily understood. The feed rollers are constructed with grooved peripheries whereby they may readily *engage the rod to be polished and are carried by the shafts which are journaled in and extend through the bearings 5., a gear 9 being secured upon the end of either or both of said shafts and connected with the actuating motor so that the said feed rollers will be positively rotated in the operation of the device. At intervals along the body 1, I construct radial recesses or chambers 10 which open at their inner ends into the bore 7 and have plugs 11 fitted in their outer ends, as shown. Between the chambers 10, bushings 12 are fitted in the bore 7 of the body and these bushings are interchangeable and have external diameters corresponding to the diameter of the bore of the body 1 while their internal diameters are suflicient to causethem to fit closely to the rod to be polished but not small enough to bind on said rod. Ihe bushings, therefore, serve as guides and supports for the rod in its movement through the body and also serve to remove the large rouglnparticles which may be upon the rod when it is received at the polishing apparatus. Between the opposed ends of adjacent bushings, I fit the polishing blocks 13 which may be of hard wood or any other material which will hold the polishing compound to the work. These blocks are provided with grooves 14 in their opposed faces which receive the rod and are also constructed with small openings 15 through which the polishing compound may escape to the work. The polishing blocks are of such length and width that they will fit easily within the respective recesses or chambers 10 of the body and are disposed against the inner faces of receptacles or boxes 16 which carry the oil or polishin material. These boxes are constructed with no i register with the openings 15 in the polishing blocks and the outer sides of the boxes are closed by cap plates 18 which are held to the boxes by springs 19 bearing against the boxes and the plugs 11, as shown. A filling tube 20 is inserted centrally through the plug 11 and has its inner end screwed or otherwise rigidly secured inthe cap plate 18, the springs 19 being coiled around the said filling tube, as clearly shown in Fig. 3. The outer end of the filling tube is closed by a plug 21 and has sufficient clearance in the plug 11 to play freely therein, the spring 19 serving to hold the polishing block to the Work with a constant tension. By adjusting the plug 11, the tension of the spring 19 may be regulated and the box 16 may be adjusted radially so as to permit the use of the device for polishing a larger or a smaller rod, as may be necessary.

It is thought the operation of the device will -be readily understood from the foregoing description, taken in connection with the accompanying drawings. It is obvious that the rod must be held against rotation while it is fed through the body 1 which is rotated at a high speed. The feed rollers 8 will grip the rod with such a degree of firmness that the operator will have no trouble in preventing rotation of the rod as it passes through the rotating body 1. After .the end of the rod emerges from the delivery end of the rotating body, it may be grasped by the operator and rotation of the rod then manually prevented without eflfort. If the feed rollers be omitted and the body 1 secured against rotation, the rod to be polished may be rotated as it is caused to pass through the body and the desired results thus obtained, but I prefer to hold the bar or rod against rotation and rotate the polishing body. The bushings 12 may be readily interchanged so that bushings of proper diameter to accurately accommodate and fit the rod to be polished may be employed. The oil or other polishing material is fed through the tubes 20 into the boxes 16 and from said boxes will escape through the outlets 17 and 15 to the work and the rapid rotation of the polishing blocks 13, in conjunction with the flow of the polishing material into the slight space between the blocks and the rod will quickly produce a high polish on the surface of the rod. When the polishing blocks are to be renewed, it is necessary merely to remove the plugs 11 at the outer ends of the proper radial chambers or recesses of the polishing body, whereupon the boxes 16 and the polishing blocks will be withdrawn and new parts may be easily substituted. The boxes which contain the polishing material and the parts which coact therewith are all inclosed in the polishing body so that damage thereto by accidental contact with adjaeases? comprising a polishing body having a Ion-- gitudinal bore to receive a rod to be polished, polishing blocks fitted within the body and projecting within the bore of the same to engage the rod, and means for supplying 1 polishing material to the said blocks.
